In the Linux kernel, the following vulnerability has been resolved:sh: push-switch: Reorder cleanup operations to avoid use-after-free bugThe original code puts flush_work() before timer_shutdown_sync()in switch_drv_remove(). Although we use flush_work() to stopthe worker, it could be rescheduled in switch_timer(). As a result,a use-after-free bug can occur.
